Adding instrumentation for graph-explorer about graph-explorer

[pcn]

Quick note:

I've been testing in a virtualenv:

virtualenv ~/venvs/graph-explorer
. ~/venvs/graph-explorer/bin/activate
pip install python-statsd
pip install decorator
./graph-explorer.py

I actually haven't pointed this at a statsd setup (no access from my home to company statsd, haven't set-up bucky+graphite on my laptop yet) but I've verified that datagrams are being sent that look about right when I enable this (I'm sending to www.google.com 8125 based on the premise that they'll forgive a few bytes getting dropped by their firewalls).

509 pn@pn-mac 14:32 ~ $ sudo tcpdump -A -i en1 udp and port 8125
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on en1, link-type EN10MB (Ethernet), capture size 65535 bytes

etc.

i'm gonna close this because from what we last discussed, it's not a finished solution that could be merged.
that said, if you want to touch base on this again, i'll gladly help out.
